Application filed February This invention relates to loose leaf bindersand more particularly to the back or cover members thereof.

One of the objects of the invention is the provision of a loose leafbinder back or cover having a new and improved means for con necting thehinged, to the attaching portion of said back or cover member.

Another object of theinvention is a new and improved process of makingcover or back members for loose binders. 7

further object of the invention is the provision of new and improvedloose leaf binder or cover member that is provided 'with an attachingportion and hinged portions connected together by novel means wherebythe finishing. clot-l1 will not be abruptly bent or folded in openingthe cover or back members. 4

A still further object of the invention is the provision of a new andimproved cover or back member that is cheap to manufacture, easilyassembled, neat in appearance, light, durable, and one in which thefinish mg or covering member will not readily become chipped, broken ordisfigured at the hinge by use. I,

Other and further objects and advantages of the invention will appearfrom the fol lowing description taken in connection with theaccompanying drawings, in which Fig. 1 is a plan view of the reinforcingmember;

Fig. 2 is a plan view of the reinforcing member and finishing covershown in partly assembled position;

Fig. 3 is a plan view of the inner side of the back of a loose leafbinder, shown as completely assembled.

In the manufacture of covers or back members for loose leaf binders andthe like it is the common practice to employ a reinforcing membercomprising two separate sections on one side of which the finishingmember, usually of imitation leather, is attached by glue, paste or thelike. The two sections are spaced slightly apart and the portion of thefinishing member extending between the two sections of the backor covermember constitutes a hinge for the cover. But this arrangement isobjectionable because the assembling of the parts is done by hand, whichis not only a slow process but it is inaccurate because of lack ofuniformity in the spacing of the sect-1011s by the work- 4, 926, SerialNo. 85,821.

men. Furthermore, in this form of con These and various otherdifficulties and objections have been overcome in the binder member andmethod of making the same, that will now be described. j

In'the form of the device selected to illustrate one embodiment of theinvention, the reference character 10 designates what for convenience ofdescription will be termed a between the sections, and since THE DAVIDramonnoYQ back'member for a loose leaf binder. This backmember comprisesa reinforcing member 11 which may be of any suitable material, usuallyof fiber, in some instances semirigid as cardboard, and in others moreor lless flexible, and a finishing member or cover The reinforcingmember 11 is weakened along a line adjacent to one of its ends whereby ahinge is formed between the two sections into which the member isdivided by said line. As shown, one or more slots 13 are formed in themember 11 adjacent one end thereof, thereby dividing said member into anattaching section 14 and a hinged section 15, the two sections beingconnected together by one or more connecting portions 16. As shown, asingle slot is made and a connecting portion 16 is left at each end ofthe slot.

The finishing material or cover member 17 is then pasted or otherwisesecured on one side of the back and its side edges 18 folded over andpasted on the opposite side of said back, after which the ends 19 and 21are folded over onto the opposite side of said back member and pasted orglued in posi-' tion. It will be noted that the body of'the cover memberand edges 18 and the end 19 assist. in forming the hinge between theattaching and hinged sections of the back. By securing the cover memberfirmly to both sides of the connecting portions 16 the cover member notonly reinforces the hinge connection but also assists in preventingsharpbending of the connecting portions 16, and consequently these connectingportions will continue to function as hinge members almost indefinitelywithout cracking or chipping the coating; on the finishing member.

hand and renders it possible to assemble the parts by machinery, thusinsuring rapidity and accuracy in the process of assembly.

,Whetherthe binders be assembled by hand or by machinery, uniformity insize is in-,

su'red. Furthermore, the use of connecting); strips between "theattaching and hinged section of the reinforcing member, whether the samebeg integral therewith or securely attached thereto, forms a hingebetween the sections that will prevent sharp bending of thefinishingcloth or cover with the consequent chipping of the coating thereon,therebynot only preserving the appearance of the binder but alsoextending its life.

It is thought from the foregoing taken in connection with theaccompanying drawings that the construction and operation of my devicewill be apparent to those SlilllEd 1n the art, and that various changes111 size,

' shape, proportion and details of construction 'may be inade Withoutdeparting :t'noin the spirit and scope of the appended claims.

I claim as my invention: a '1. In a binder for leaves, a boardcomprising an attaching member, a hinged member, strips structurallyintegral with said memberst'or connecting the same together for holdingthem in spaced relation, a fiexihie cover extending over the outside ofsaid board and secured thereto, and having .a portion extending from oneof said members to the other over the inner side of said strips andsecured thereto, for reintorcing the same. i i I a 1 2. A back for aloose leaf binder comprising a reinforcing member including an attachingsection and a hinged section spaced therefrom, strips structurallyintegral with said sections for connecting said sections for forming ahinge theretor, and a flexible finishing cover pasted to one side ofboth of said sections.

In testimony whereof I aihn my signature.
